$1.($True or False$)$ The Induction machine is a type of synchronous machine.

$2.($True or False$)$ The Synchronous machine is a type of synchronous machine.

$3.($True or False$)$ An induction machine may be singly$-$fed or doubly$-$fed.

$4.($True or False$)$ An induction machine may be connected in wye or delta.

$5.($True or False$)$ In variable speed drives applications the induction machine is connected

in delta.

$6.($True or False$)$ An induction machine is used in generation most often in wind energy

applications.

$7.($True or False$)$ Stall$-$torque is the torque a machine can deliver when it is operating at its

rated speed.

$8.($True or False$)$ Pull$-$out or maximum torque is the torque a machine can deliver at

stand$-$still.

$9.($True or False$)$ An induction machine operating at maximum torque is not necessarily

operating at its most efficient point.

$10.($True or False$)$Slip$$ is the metric associated with an induction machine and is the

difference between synchronous speed and actual speed, scaled by synchronous speed.

$11.($True or False$)$ Induction machine core losses are primarily associated with the stator.

$12.($True or False$)$ In general the better the machine quality the higher Rc and Xm will be$.$

$13.($True or False$)$ At $$stall$$ you can easily find the output torque by taking Pout $/$wm$.$

$14.($True or False$)$ At maximum torque $($pull$-$out$),$ the machine will operate at maximum

$$slip$$ and at minimum PAG.

$15.($True or False$)$ Data for R$1,$ X$1,$ Rc $,$ Xm $,$ R$1,$ and X$2$ can be found by conducting tests that

follow the IEEE $112$ Standard.

$16.($True or False$)$ Synchronous machines are either $$wound field$$ or $$permanent magnet

field$.$

$17.($True or False$)$ Synchronous machines that are $$wound field$$ find their greatest use

generation.

$18.($True or False$)$Wound field$$ synchronous machines often employ what is known as an

$$exciter$$ stage.

$19.($True or False$)$ Frequencies of variables associated with the rotor of an induction

machine are at the excitation frequency.

$20.($True or False$)$ All machines have a $$torque vs$.$ speed$$ curve, but they differ from each

other based on how the machine operates.
